After the crude oil has passed the separation process it is led into a refinery. Here it is split into high-value products such as fuel, kerosene, naphtha, lubricant oil, LPG and also asphalt and petroleum coke. Whilst slowly heating the crude oil, its various components can be extractedeach at a specific temperature. Most
high. For example, in a 300,000 bbl/d oil refinery, if one part per million by weight of the oil is deposited in the pre-heat exchanger train, in one year about 15 tonnes of solid carbonaceous deposits will have accumulated. This
The heat exchanger calcium sulphate fouling in tube side is the deposition on the tube surfaces which affect the heat transfer. It’s found that the oil refinery process plant having an issue of

• Crude oil distillation is more complicated than product distillation, in part because crude oils contain water, salts, and suspended solids. • Step 1 in the refining process is to remove these contaminants so as to reduce corrosion
fluid may either be process fluid or a heat transfer fluid. They are used for pre-heating crude oil and other feed stocks for many refinery processes where the use of steam from boilers may not be practical. One of the problems
A typical refinery consumes between 350,000 and 550,000 British thermal units (Btu) of energy for processing one barrel of crude oil. In recent years, refineries have made significant progress in heat integration; however, fouling of
challenging refinery’s objectives. Sulzer has the requisite person-nel, experience, facilities, as well as engineering capability to model and analyze mass and heat transfer phenomena in distillation, absorption, extraction, mixing
Introduction An oil refinery includes many unit operations and unit processes. A unit operation is a basic step in a process. Like evolution of our planet, life and technology, oil refining industry has been developing with increasing complexity since its foundation in 1859. Unit operations involve
